ROLL-SIDE-BEQISTEBING MECHANISM.

Application filed March 25, 1926. Serial No. 97,170.

This invention relates to roll change mechanism and has moreparticularly reference to means for adjusting the web roll or itssupporting means lengthwise so as to sideregi'ster the web.

In the art of roll change mechanism it is now the custom to provide aplurality of web rolls and to provide a backing member, usually of aflexible character, that bears against the employed web and to bring areplenishing roll against the employed web so that the two webs or theroll and web be pasted together. When it is now attempted to move'theroll lengthwise so as to side-register the web, the flexible backingmember will drag on the web or roll and is apt to tear it, and the mainobject of this invention is to prevent such tearlng action.

\ Accordingly the invention consists in providing means whereby, whenthe roll or 1ts support is adjusted lengthwise, the backing member willlikewise be adiusted so that there is substantially no relative motionbetween the backing member and the web.

In the accompanying drawings the invention is disclosed in severalconcrete and preferred formsin which:

Fig. 1 is a view in end elevation and somewhat diagrammatic in form ofa. device embodying one form of the invention.

Fig. 2 is a side elevation of the parts shown in F1 '1.

Fig. 3 is a detail plan view in section of part of the gearing.

Fig. 4 is a view similar to Fig. 2 but showing a modified form of theinvention.

Fig. 5 is a view similar to Fig. 1 but shpwing another modified form oftheinvenhon.

Fig. 6 is a vertical sectionalview on the plane of line 6-6 of Fig. 5.

Fig. 7 is a horizontal sectional view on the plane of line 77 of Fig. 6.

1 indicates a web-pulling machine such as a printing machine and 2 is arota able support in the form of a shaft 3 having spiders 4 at itsopposite ends. Spiders 4 carry a plurality of rotatable rolls, 5, 6 and7, one of which (5) is shown employed or in feeding position. 8 is abacking member taking here the form of a flexible canvas sheet carriedby shaft 9 and having weights 10 at its free end. As shown this canvasbears against roll 5 and, when it is desired to make a roll change,paste is applied to roll 6 and shaft 3 is turned by hand or areplenishing roll is otherwise moved. into position until it comes incontact with web 11 from roll 5, backing member 8 exerting sutlicien'tpressure to admit of the two webs being united, and the turning movementof 3 is continued until roll 6 occupies the position of roll 5. Shaft 3may be adjusted in various ways. For instance pedestals 12 and 13inaybemoved carrying the shaft with it, or, as here shown, pedestal 13may slide in ways 14 and by reason of collars 15 and 16 may'carry shaft3 with it. In these circumstances shaft 3 ma be loose in pedestal 12,that is: it'may sli e freely in the bearing of the pedestal. Anysuitable means may be provided for moving pedestal 13 and shaft 3. Inthe present instance there is a motor 17 mounted to slide with thepedestal, and shaft 18 of said motor carries-a bevel gear 19 meshingwith a similar bevel gear 20 on shaft 21. Shaft 21 carries a worm 22meshing with worm gear 23 on shaft 24 and the end of this shaft isthreaded as at 25 to engage an internally threaded bushing 26 carried bythe framework independently-of the pedestal and consequently rotation ofthreaded shaft 25 will move the pedestal in one direction or the otherin accordance with the direction of rotation, and will thus move shaft 3and the spiders endwise. Motor 17 is of the reversible type.

Shaft 9 is slidable in bearings 27 and has a threaded portion 28engaging internally threaded bushing 29 carried by bracket 30 of theframework. Said bushing also carries-a sprocket 31 connected by means ofchain 32 with s rocket 33. Sprocket 33 is mounted on sha 34 which latteris slidable with respect to the sprocket and is, like shaft 24, carriedby pedestal 13. Spur gears 35 and 36 connect shafts 24 and 34.

It will now be seen that when shaft 3 is moved endwise shaft 9 islikewise moved and in synchronism therewith and consequently backingmember 8 is shifted in synchronism with the web roll against which itbears.

In Fig. 4 is shown a modified form of the invention in which the backingmember consists of two canvas sheets 37 and 38 mounted on shaft 9.

In Figs. 5, 6 and 7 is shown a second mod ified form of the invention.Here backing member 39 is in the form of a canvas hung from shaft 9 asbefore, but in addition thereto the lower end thereof is anchored by nomeans of spring on slidable member or anchorage 41. Member 41 is movedlongitudinally by the same kind of a connection as 30, 31and 32, powerbeing derived from shaft 84 by means otsprocket 42 with the result thatboth shaft 9 and member 41 are moved endwise in synchronism'with supportor shaft 3.

In all of the forms shownp support carrying a plurality of rolls isdisclosed, but it will be understood that, if desired, support 3 maycarry only one roll.-
